/* ramtt-drawings.css · shared by the components of sources/ramtt-drawings.mjs: RAMTT's line drawings,
   the login door's scenes, the identity pieces and the instruments. Each stands in a frame of its own.
   The surfaces and inks are RAMTT's paper and ink as the drawings were delivered (#fcfcfb, #0b0b0b), and
   what moves takes the accent, violet-500 of exilinar III (#6250d6); the controls follow Tau: Inter, weights
   450 and 500, a press is a capsule, a field has a radius of 8, a panel 12, and a first-order response of 50 ms on every state. */
